WILLIAM S. G. BAKER, OF BALTIMORE, MARYLAND.

CAR-AXLE BOX.

SPECIFICATION formingpart of Letters Patent No. 247,236, dated September 20, 1881, Application filed July 1, 1881. (No model.)

To all whom it may concern Be it known that I, WILLIAMS. G.BAKER, of the city and county of Baltimore, State of Maryland, have invented a new and useful Improvement in Cars, of which the following is a specification.

My invention relates to that class ofjournalboxes and pedestals (adapted to four or six wheel trucks) in which the journal-box is fitted to move vertically and laterally within the jaws of the pedestal, the box being arranged with a saddle on top, in which rests a link or yoke suspending a carriage, on which the springs set within the pedestal upon which the truck-frame rests. The top part of the journal-box has a recess, in which is set a hearing or saddle, which, when worn out, can be removed and replaced, thus preventing injury to thejournal-box housing. This hearing or seat has a recess to accommodate the link or yoke, which can be made of round iron. The spring-carriage extends beyond each side of the box into openings in the sides of the pedestal and forms upon each side a seat, upon which it carries the spring. The spring-carriage is made to take a square bearing on each side opening in the pedestal, so that it can move vertically, but cannot twist or move laterally- Through its floor are two oblong holes, in which the link or yoke can play laterally.

Where a link is used to suspend the springcarriage there is in the middle of the bottom of the spring-carriage, connecting the two oblong holes, a longitudinal slit, through which the link is dropped. A movable lower seat or washer is then slipped into place, resting on the upper surface of the lower part of the link, and when the link is drawn up this washer or seat rests also against the under surface of the bottom of the spring-carriage and forms a bearing for the link. This permits the link and box to work laterally, while the spring-carriage can work vertically only in combination with the link and box.

Where a yoke is used to take the place of the link its ends pass through the oblong holes in the bottom of the spring-carriage, which, on its under surface, is made concave. The ends of the yoke also pass through and are firmly secured by nuts to a half-round washer, which thus becomes part of the yoke. This half-round washer fits into and works in the concave un der surface of the bottom of the spring-carriage, and it takes the place of the lower part of the link above described. Thus there is a large area of wearing-surface, which is easily removed and replaced when worn out.

My invention also relates to a box in which the car-axle is housed. This has an adjustable bearing, a projecting sleeve upon the inner end of the box, and an annular ring cast upon the face of the car-Wheel, the sleeve of the box projectin g into the ring of the wheel. Leather or fiber washers are placed between the end of the sleeve on the box and the face of the wheel, and between the face of the annular ring on the wheel and the back of the box. These circular washers are held in place by suitable springs on the face of the wheel and the back of the box. These springs may be of metal or gum, and of such strength as will keep the washers in place without causing undue wear. The object is to keep the box tight, thus pre venting the escape of oil and the entry of dust.

The wheel cannot change'its relation to the box, being held in place by a forked stopwedge, as more fully hereinafter described.

In the accompanying drawings, forming a part of this specification, Figures 1, 2, and 3 representthe arrangement where a yokeis used. Figs. 4, 5, and 6 represent the arrangement where a link is used. Fig. 1 is a cross-section of the box and pedestal, showing axlebearing H, stop wedge or key W, packing-rings K K, and springs S S. Fig. 2 is a half-elevation and half cross-section of elevation. Fig. 3 is an elevation of yoke Y, spring-carriage G, and yoke washer X. Fig. 4 is an elevation showinglink. Y and washer X. Fig. 5 is a cross-section of the link-seats on top of the box and under the spring-carriage. Fig. 6 is a plan top view of the spring-carriage and a cross-section of the pedestal and link.

Similar letters represent similar parts.

The pedestal P is made preferably of castiron, and is secured to the frame of the truck by bolts. The axle-box A slides freely vertically and laterally in the jaws of the pedestal P.

D represents the hub of the wheel with the annular ring 0 cast thereon,into which extends the ring B, formed on the back of the box A. This ring B may have a flange on its outer side,

link or yoke Y rests.

which is faced oif smooth and comes in contact with the washer K, fitting closely on the axle T. Between this washer K and the face of the wheel is inserted acircular tube-washer, S,forn1- ing a spring. There is also a similar washer, K, bearing against the face of the annular ring G, cast on the wheel D, with a similar spring, S, inserted between it and the back of the box. The axle T, upon which the wheel D is fitted, passes into the box A from the back, and is held to the box by the forked stop wedge or key W, fitting in the annular recess I at the outer end of the axle T, and also fitting into the recesses A in the sides of the box A. The spaces in which the circular gum-tube washers S and S rest are less in width than the diameter of the tubing, so that when the box A is shoved into place to allow the entryof the key or stop wedge W the tubing S S will be compressed, giving sufficient force to keep the washers K and K close up to their bearings without in aterially increasing the friction.

The lid L is held in place by a bolt or otherwise, and its inner top side is provided with a gum or other cushion, 0, bearing on the top of the key W, to prevent it from rattling when in use. The box is provided with oilers F, made with metal frame and felt feed.

The journal-box A has on top a recess, Z, in which sits a saddle, D. This saddle has a con cave or circular seat or hearing, in which the Where a yoke is used its arms extend on either side of the box A, passing through the oblong holes N in the spring-carriage G, into and through the halfround washer X, to which they are firmly secured by nuts U U. The under side of the spring-carriage G is concave, and fitting into it is the half-round seat or washer X, attached to the yoke Y. Where a link is used it is dropped through the slit N in the spring-carriage G. The washer X is then dropped into place between the link and the bottom of the spring-carriage, and rests upon thelink. The upper side of the link is then slipped over and dropped into the recess in the saddle D, resting upon the box, thus suspending the springcarriage G and holding it and the box A together. This permits the link or yoke Y and the box A to have lateral play and vertical play, while the spring-carriage G can have vertical play only within the pedestal P. Thus there is no unnecessary strain on the springbolts or car-springs 1%, while the saddle D and washerX,upon which the principal wear comes, can be readily removed and replaced.

I claim as my invention- 1. The combination, with face of the wheel and the end of the axle-box, of a spring-actu' ated washer, K, substantially as described.

2. The combination, with stopwedge, of a cushion, 0, bearing upon said wedge and the upper part of the box or lid, substantially as described.

3. The movable bearing D on top of the oilbox A, forming a seat for the link or yoke Y, as and for the purposes set forth.

4. The spring-carriage G, resting on a movable seat, X, suspended by a yoke or link, Y, as and for the purposes set forth.

5. The link Y and movable washer X, suspending the spring-carriage G and holdingit and the box A together, as and for the purposes set forth.

6. The combination of an axle-box, A, movable bearing 1), link or yoke Y, and WasherX, suspending a spring-carriage, G, so as to allow vertical motion only to the spring-carriage and vertical and lateral motion to the axle-box.
